I am currently in the DEP for the USAF and leave in January. I am 18 and once I get stationed, I do not plan on buying a car. I am an avid mountain biker and in great shape. I was just wondering if anyone had any ideas for commuting once I am stationed. Unfortunately, I do not know where it will be yet. What kind of bag do you use or your setup? Mountain bike?, hybrid?, single speed?. Any ideas? Thanks!
